Welded steel pipe for piping

We offer a wide range of services, from the manufacturing of pipes with irregular lengths to the construction of open ends!

The product we are introducing this time is welded steel pipes for piping. When manufacturing pipes, there are often limitations on the production lot size and minimum length. However, at Benkan Kiko, we can accommodate customer requests for standard lengths such as 4000L, 5500L, and 6000L, as well as shorter sizes under 1M and intermediate lengths known as random lengths, along with the construction of end preparations. Regarding welding construction, we can also handle welding work based on regulatory requirements such as the Electric Utility Industry Law, Gas Utility Industry Law, boilers, and first-class pressure vessels. For products subject to the Electric Utility Industry Law, we can provide welding methods and quality assurance through certified welders that comply with inspections for welding contractors, contributing to cost reduction for our customers through the preparation of documentation related to inspections and factory audits. Additionally, further cost reductions can be achieved by performing circumferential welding of joints and pipes together.
